# AI Video Transcriber & Translator

This tool extracts audio from videos, transcribes it using OpenAI's Whisper model, and translates the transcript using Google's Gemini API.

## Setup

1.  **Install Dependencies:**
    ```bash
    pip install -r requirements.txt
    ```
    *Note: You need `ffmpeg` installed on your system.*

2.  **API Key:**
    Set your Gemini API key as an environment variable:
    ```bash
    export GEMINI_API_KEY="your_api_key_here"
    ```

## Usage

### Quick Start (Wizard)
For a user-friendly, interactive experience, run the wizard script in the root directory:

```bash
./run_wizard.py
```
This will guide you through selecting files, languages, and enabling features like cleanup and embedding.

### Advanced (CLI)
Run the `main.py` script directly:

```bash
python ai_transcriber/main.py <path_to_video_or_folder> [options]
```

### Options:
*   `--model`: Whisper model size (`tiny`, `base`, `small`, `medium`, `large`). Default: `base`.
*   `--lang`: Target language for translation. Default: `English`.
*   `--force`: Overwrite existing transcript/translation files.

### Examples:

**Single File:**
```bash
python main.py ../my_video.mp4
```

**Entire Directory (Recursive):**
```bash
python main.py ../videos_folder/ --lang "Spanish" --model small
```
